Wow! Is that the APR 300? Looks good but my guess is that you need less angle of attack than you have in the pics. I would think you'd have a high speed push with that setting. How was it though Turns 4, 9 and 10?

I was messing around with my coilovers this weekend working my more shock travel project...see link below

As I was doing this I go to wonder just how much can you cut down bumpstops before they are just too short to do their job properly?

Yeah, it's GTC-300. I had it set on second setting from very top.... I think it gave me like 7-9 degrees AOA on the edges and 1-3 degrees in the middle.
I can't really access the effects properly without having a data from the track, hence one of the next things I'm trying to pick up would be a GPS/datalogger. My subjective opinion is that it gave me a piece of mind and more confidence.
The only thing that I can tell is that with my HTRZ-3s (10k springs, Whitiline front sway, 9F/8R out of 14 dampening, 31psi hot all four)I was going 122mph before turn 1 and 91mph through turn 4 (shute?) That was with 7/10 effort/concentration.

Thanks for the compliments!
But yeah...next thing for me would be:
R-comp tires
splitter
GPS/datalogger
GoProHD2

Getting Eibach front swaybar in at some point also. It is not solid like Whiteline and less stiff. I want to see if I can get away with it.

You need to be 0 or minus in the middle. Probably the latter because of the larger surface area.

And I have no reason to kep my DL1 datalogger. Would be willing to part with it cheap.

So I was looking through the info that APR has:
And it looks like GTC-300 AOA difference between middle and ends is 15.2 degrees. I need to remeasure what I have and adjust accordingly.
Skip, let me know how much would you want for datalogger! I'm interested!

Oleg, remember when you're measuring the wing it's relative to level ground. The air that comes up and over your roofline does not hit the wing parallel to the ground. On a wing that big, I'm guessing -3* would be a good starting point for the middle section. Rob would probably be able to offer a more scientific starting point.

DL1... will have to get back to you on that. I know how much I paid for it used. Obviously I'm not going to get but maybe half of that.
